I’ve started playing with druid and got a basic setup working with indexing service. I’m indexing a kafka stream using storm + tranquility and it seems to be working fine. I’ve also setup pivot UI pointing to the druid broker node.
Initially during indexing, I observed that none of the “dimensions” were showing up in the pivot UI. I could only see “Time” field showing up. I tried restarting pivot and doing introspection of the schema several times, but it didn’t pick up the dimensions.
But after the index segment got handed off to the deep storage and started getting served by the historical node, I could see all “dimensions” appear after a pivot UI restart.
I’m curious as to why the “dimensions” didn’t show up when the query was hitting the “realtime index”. Can anyone help me understand if this is expected ? If not, any suggestions on what to look for ? Let me know if any more info is required.
